Nov yog ib lo lus nug uas kuv nyiam nug cov thawj coj hauv khw muag khoom precision: thaum twg yog zaum kawg koj tau ntseeg koj lub phaj nto?
Tsis yog "nws zoo li tiaj tus." Tsis yog "nws dhau qhov kev tshuaj xyuas tuaj." Kuv txhais tau tias ntseeg siab - hom kev ntseeg siab uas koj muab ib feem tshiab rau nws, ntsuas koj cov kev ntsuas, thiab paub tias cov lej koj nyeem yog hais txog qhov khoom, tsis yog hais txog lub phaj uas nyob hauv qab nws.
Feem ntau cov neeg ua siab deb. Ib txhia hloov lub ntsiab lus. Ob peb tug lees tias lawv tsis paub, vim lawv yeej tsis tau kuaj xyuas.
Qhov ntawd yog qhov pib rau tag nrho cov kev sib tham no.
Vim Li Cas Cov Phaj Nto Tseem Tseem Ceeb Ntau Dua Li Cov Neeg Yuav Khoom Feem Ntau Xav
Peb nyob hauv lub caij nyoog uas muaj cov laser interferometers, cov tshuab pom kev, thiab cov khoom siv kov uas tuaj yeem ntsuas cov yam ntxwv me me hauv vib nas this. Nws yooj yim kho lub phaj saum npoo zoo li cov khoom qub - pob zeb tiaj tiaj (lossis hlau cam khwb cia hnyav) uas nyob hauv kaum ntawm chav tshuaj xyuas tsis ua dab tsi li.
Tsuas yog nws ua yuav luag txhua yam.
Lub phaj nto yog lub dav hlau siv los ntsuas feem ntau ntawm kev ntsuas tes thiab ib nrab ntawm kev ntsuas tes. Txhua qhov nyeem micrometer uas koj ntsuas nrog lub ntsuas qhov siab, txhua qhov teeb tsa qhov ntsuas, txhua qhov kev sib piv ntawm cov khoom siv tshuab thiab tus qauv siv - tag nrho nws ntws los ntawm qhov chaw uas qhov khoom zaum. Yog tias qhov chaw ntawd tsis ruaj khov thiab tsis tuaj yeem kwv yees tau qhov kub, txhua qhov kev ntsuas hauv qab muaj qee qhov yuam kev tsis suav.
Qhov tseeb tsis xis nyob yog tias feem ntau cov khw muag khoom siv kev tswj xyuas zoo ntawm cov hauv paus uas lawv tsis tau nug txog ntau xyoo. Qee zaum ntau xyoo.
Cast Iron vs. Granite: Qhov Sib Piv Tseeb Tsis Muaj Leej Twg Ua Tau Zoo
Taug kev mus rau hauv kaum lub chaw tsim khoom precision thiab koj yuav pom kwv yees li 50/50 faib ntawm cov hlau cam khwb cia thiab cov phaj granite. Nug cov neeg yuav khoom vim li cas lawv thiaj xaiv qhov lawv xaiv, thiab feem ntau yuav muab cov lus teb rau koj uas zoo li tsim nyog tab sis tsis tuav tau kev tshuaj xyuas.
Kuv xaiv hlau cam khwb vim nws yog ib yam khoom qub.
Kuv xaiv granite vim nws ruaj khov dua.
Ob lo lus teb no tsis tiav. Nov yog qhov kev txiav txim siab tiag tiag zoo li cas:
Cov phaj hlau cam khwb ciatau ua tus qauv kev lag luam rau ntau tshaj ib puas xyoo, thiab rau cov laj thawj zoo. Lawv muaj cov yam ntxwv zoo heev - lawv nqus tau kev co zoo dua li granite, uas tseem ceeb hauv cov chaw ua haujlwm hnyav. Lawv kuj yooj yim dua rau rov ua dua thaum lawv hnav. Tus kws kho tshuab txawj tuaj yeem khawb lub phaj hlau uas hnav rov qab mus rau qhov kev qhia tshwj xeeb sai sai, uas ua rau kev saib xyuas yooj yim.
Qhov kev pauv pauv yog qhov rhiab heev ntawm qhov kub. Cov hlau cam khwb cia nthuav dav thiab cog lus pom tseeb nrog kev hloov pauv kub. Lub phaj hlau cam khwb cia hauv lub khw tsis muaj cua sov thaum lub caij ntuj no ua haujlwm txawv ntawm tib lub phaj thaum lub caij ntuj sov. Rau cov haujlwm uas xav tau kev ua haujlwm raug micron-level hla kev ntsuas loj, qhov kev hloov pauv thermal no tsis yog qhov yooj yim.
Cov phaj granite ntodaws qhov teeb meem thermal zoo nkauj. Cov granite dub muaj cov coefficient thermal expansion qis heev thiab qhov ruaj khov ntawm qhov kub thiab txias ib txwm muaj. Lub phaj granite tsis xav tau kev tswj huab cua kom tuav nws cov geometry zoo li cov hlau cam khwb cia. Nws kuj tsis yog corrosive, tsis xeb, thiab tsis xav tau roj.
Qhov kev pauv pauv yog kev kho tau. Thaum lub granite nto hnav lossis puas lawm, koj tsis tuaj yeem khawb nws rov qab mus rau qhov kam rau siab li koj ua tau nrog cov hlau cam khwb cia. Koj tab tom nrhiav kev rov ua dua (kim thiab siv sijhawm ntau) lossis hloov pauv. Qhov no yog vim li cas qhov zoo ntawm cov khoom siv thawj zaug thiab kev ua haujlwm raug tseem ceeb dua rau granite - koj tab tom ua kev cog lus mus sij hawm ntev ntawm qhov chaw yuav khoom.
Qhov tseem ceeb tiag tiag hauv daim teb: rau feem ntau cov ntawv thov tshuaj xyuas hauv cov chaw tswj hwm, granite lub thermal stability muab nws qhov ntug ntsuas tau. Rau kev siv tshuab hnyav thiab kev sib dhos loj qhov twg kev co damping thiab kev kho tau tseem ceeb, hlau cam khwb cia tseem khwv tau nws qhov chaw.
Lub Txheej Txheem Qib Piav Qhia: Koj Yuav Dab Tsi Tiag
Feem ntau cov lus qhia ntawm cov phaj nto siv cov qauv xws li DIN 876, ASME GGGP-463C, lossis ISO 8512. Cov qauv no txhais cov qib raug - feem ntau yog Qib 00, Qib 0, Qib 1, thiab Qib 2 - raws li kev kam rau siab.
Nov yog cov qib ntawd txhais li cas hauv kev xyaum, siv tus qauv DIN 876 ua piv txwv:
Qib 00 tso cai kwv yees li 2.3 microns ntawm qhov sib txawv ntawm qhov tiaj tiaj tshaj 1,000 hli. Qib 0 tso cai kwv yees li 4.6 microns. Qib 1 tso cai kwv yees li 9.2 microns. Qib 2 tso cai kwv yees li 18.5 microns.
Tus qauv ob npaug ntawd tsis yog qhov tsis raws cai - txhua kauj ruam hauv qib sawv cev rau qhov yuam kev uas tso cai ob npaug. Thiab qhov yuam kev ntawd yuav tsum tsis yog tsuas yog them rau qhov kev kam rau siab ntawm kev tsim khoom xwb, tab sis kuj tseem yuav tsum them rau qhov puas tsuaj ntawm lub phaj thaum lub sijhawm ua haujlwm.
Rau cov ntsiab lus: yog tias koj ntsuas cov khoom siv tshuab mus rau ± 2 microns, lub phaj nto Qib 1 (9.2 microns ntawm qhov sib txawv ntawm qhov chaw tso cai) twb siv yuav luag 20% ntawm koj qhov kev kam rau tag nrho - ua ntej koj suav nrog lwm qhov chaw ntawm kev ntsuas tsis meej. Qhov ntawd yog tus lej tsim nyog zaum nrog.
Qhov no yog vim li cas cov chaw kuaj mob metrology loj thiab cov tshuab aerospace zoo yuav luag txhua tus qhia txog Qib 00. Tus nqi ntxiv ntawm cov phaj qib siab dua yog qhov tsis tseem ceeb piv rau tus nqi ntawm qhov yuam kev ntsuas tsis pom uas nkag mus rau hauv ib pawg ntawm cov khoom tsis sib xws.
Dab tsi tua koj lub phaj nto kawg (Thiab Dab Tsi Zoo Tiv Thaiv)
Cov phaj nto tsis ua haujlwm hnyav heev. Lawv ya mus los. Lawv nqus cov dej noo. Lawv khaws cov kev puas tsuaj hauv qab ntawm cov khoom ua haujlwm poob. Lawv tsim cov qauv hnav hauv zos los ntawm kev sib cuag ntau zaus nrog tib qho chaw ntsuas.
Qhov feem ntau ua tsis tiav rau cov phaj hlau cam khwb cia hauv qhov chaw noo noo yog qhov hloov pauv ntawm qhov loj me los ntawm dej noo. Txawm tias muaj roj zoo, cov hlau cam khwb cia muaj qhov txaus kom nqus tau cov pa dej dhau sijhawm, tshwj xeeb tshaj yog nyob rau hauv cov chaw tsis muaj kev tswj hwm huab cua. Qhov tshwm sim yog qhov qeeb qeeb, poob ntawm qhov tiaj tiaj uas tsis tshwm sim ntawm daim ntawv pov thawj calibration tab sis tshwm sim txhua zaus koj sim tuav qhov kam rau siab.
Cov phaj granite ua tsis tiav txawv. Qhov teeb meem feem ntau tsis yog teeb meem zoo ntawm granite - nws yog teeb meem thermal shock. Lub phaj granite uas tau zaum hauv lub tsev khaws khoom txias thiab tom qab ntawd tsiv mus rau hauv chav tshuaj xyuas sov thiab noo noo tuaj yeem ntsib kev ntxhov siab hauv zos uas tsim cov kab nrib pleb me me hauv qab av. Qhov no tsis tshwm sim nrog kev hloov pauv kom zoo, tab sis hauv lub ntiaj teb tiag tiag, tej yam tau txav mus sai.
Lwm hom kev ua tsis tiav rau ob qho khoom siv yog kev puas tsuaj los ntawm kev sib tsoo. Cov hlau ua haujlwm poob, kev tso tsis ceev faj ntawm lub thaiv hnyav - cov no tsim cov qhov hauv zos lossis cov cim chip uas ua rau muaj kev ntxhov siab thiab cov yuam kev geometric. Cov phaj nto zoo muaj cov khoom siv tiv thaiv tshwj xeeb los tiv thaiv qhov no, thiab feem ntau cov neeg ua haujlwm tsis quav ntsej cov lus qhia kom txog thaum lawv twb tsim teeb meem lawm.
Lub Ecosystem Accessory uas tsis muaj leej twg tham txog
Ib lub phaj saum npoo uas nyob rau ntawm lub rooj sawv ntsug uas tsis tiaj tiaj yog lub phaj saum npoo uas tsis zoo. Lub rooj sawv ntsug, txoj kev teeb tsa, thiab ib puag ncig txhua yam pab txhawb rau kev ua haujlwm zoo ntawm lub phaj.
Rau cov phaj hlau cam khwb cia, txoj kev ib txwm yog lub txee sawv nrog cov ceg kho tau. Lub tswv yim yog kom tau lub phaj hauv ob peb feeb ntawm theem, tom qab ntawd cia lub phaj nws tus kheej faib cov seem tsis sib npaug. Qhov no ua haujlwm zoo nkauj, tab sis nws xav tias hauv pem teb yog qhov ruaj khov thiab tsis khoov thaum lub nra hnyav.
Rau cov phaj granite, tshwj xeeb tshaj yog cov phaj loj, cov qauv txhawb nqa uas ruaj khov thiab monolithic tseem ceeb dua. Granite yog khov kho tab sis tawg yooj yim - nws tsis khoov kom haum rau qhov tsis sib xws me me ntawm lub hauv paus zoo li cov hlau cam khwb cia. Cov phaj granite uas txhawb nqa rau ntawm lub hauv paus tsis sib xws yuav ntsib kev ntxhov siab sib txawv uas thaum kawg tuaj yeem ua rau tawg, tshwj xeeb tshaj yog tias muaj cov voj voog thermal koom nrog.
Cov khoom siv uas tseem ceeb tiag tiag: cov khoom siv nqa khoom kom zoo kom tiv thaiv kev puas tsuaj los ntawm kev sib tsoo, lub hau npog kom tiv thaiv cov khib nyiab thiab cov pa phem kom tsis txhob nkag mus rau ntawm qhov chaw ntsuas, thiab daim ntawv pov thawj calibration tsis tu ncua los ntawm lub chaw soj nstuam uas tau lees paub. Lub phaj uas tsis muaj daim ntawv pov thawj calibration tam sim no tab tom cog lus tias nws yuav tsis rov qab tau.
